We've established that the Sony's upcoming portable wonder-machine, the NGP, isn't quite as powerful as a PlayStation 3. Further clarifying how much this thing can bench press, Epic's Mark Rein tells us that the device, which can run his company's Unreal graphics engine (think Gears of War, Mass Effect, Infinity Blade, etc), has four times the power of any other portable device Unreal's been running on, including the iPad 1.(iPad 2 not factored into this claim, he said!)
